The Schedule referred to in these Letters Patent and making art of .the same.

To all ulhom it may concern:

Be it known that I, WILLIAM GARDNER, of Catalpa, in the county of Green and State of Kentucky, have invented a new and improved Grain-Cleaner and Separator; and I do hereby declare that the following is a full, clear, andzercact description thereof, which will enable others'skilled in the art to make and use the samep referen'ce being had to the accompanying drawing forming part of this specification.

Figure 1 represents a"vertical longitudinal section of my improved grain-separator;

. Figure 2 is a plan ortopyview,'partl y in section, of

l the same.

- frame of thrashing-machine B, which is of suitable construction. The separator may, however, if desired,

be set up independent of the thrasher.

In the frame are the bearings of two horizontal shafts a b, which support and hold an endless" belt, 0. This belt is composed of two straps c c, to which a series of boxes, 11 d, is secured, the said boxes being provided with perforated bottoms, as shown in fig. 2. v

The belt 0 is loose on its drums a b. It receives motion from the same, only when it is stretched,-by means of a lever, or set of levers, H H, that are forced up by an eccentric, j, on'a revolving shaft, 9. \Vhen the eccentric forces the free end of the pivoted lever H against the belt, the latter will be so stretched as to' I be carried along by the drums at b until again slackened by the dropping of the lever. The wheat from the thrasher falls. upon the apron G, into the several boxes of the same, and passes through the meshes of the wire bottoms of the same, while the straw and coarse chaff is carried off by said belt. v 'lhe wheat, falling through the belt, drops upon a fixed plate, D, which has a series of transverse slots, through which the wheat .falls down, while the chaff, to a great extent, works outward on said plate.

During its passage from the plate D to-the shaking bottom E the wheat is exposed to a current of air from a fan, F, and is thereby entirely freedfrom all chad. A 1

Passing through the perforated shaking bottom E,

which it rolls down to be collected.

Reciprocating motion is imparted to the shaker E by means of a connecting-rod, c, or other mechanism. By the aforesaid arrangement the wheat is cleaned so well before it entersthe air-current, that but a, slight current is required; consequently, less power. is needed for operating the apparatus.

Having thus described my invention, I claim, as new and desire to secure by Letters Pat-cute; 4

fixed' slotted plate D, andreoiprocating perforated plate E, the-belt carrying a seriesof boxes, d, with perforated bottoms, as set forth.

0, for the purpose of imparting intermittent rotary motion to the same, as set forth.
